PRINTING DEVICE.

Specification of Letters Patent.

Patented May 14, 1912.

To all whom it may concern:

Be it known that I, Josnrn S'DtmoAn, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Printing Devices, of which thefollowing is a specification.

This invention relates to that class of printing devices which comprisea printing form andan information card carried by a frame, and adaptedto be stored in "accordance with a card index system or stacked in apile.

The object of the invention is to construct the frame so that the backof the card is visible and can be used for information purposes and atthe same time to strengthen the frame.

In the accompanying drawings illustrating the invention Figure 1 is afront view of the frame. Fig. 2 is a back view of the frame showing thecard. Fig. 3 shows the lower edge of the frame of Fig. 1. Fig. 4 is afront view of the frame showing the invention differently embodied. alsoa front view of the frame with the card and printing plate thereon. Fig.6 is a sectional view on the line 6-6 of Fig. 5.

Referring to the drawings, 7 is a frame which .is provided at its endswith suitable spacing flanges 8 and at its top and bottom with heads 9and .10. The printing plate 11 is detachably engaged with the head 10and lips or flanges 12 on the frame and is held in place against endwisemovement by the stop 13 andspring lock 14. Various means maybe employedfor securing the late in the frame and. instead of aprintmg plate I mayprovide the frame with a holder having type set up therein in a man nerfamiliar in the art.

The frame is provided with an opening 15 and the metal cut therefromispreferably bent over on the front of the frame to rovide a widestrengthening bead 16 and a head 17, if the opening is comparativelynarrow, as shown in Fig. 1, or to form two heads 18 if the opening iscomparatively Wide, as shown in Fig. 1. I prefer to utilize all of themetal cut from the frame to form the opening 15 to obtain the benefit ofthe strength and stifl'ness'which Fi 5 is it affords but where theopening is wide some'of the metal may have to be removed and only thenarrow beads employed as shown in Fig. 4. It has. been found that aframe having the opening 15 and strengthened at its edges by having themetal turned over thereon whichcis cut out to form the opening will bestronger and stiffer than.

improved frame thus makes the back of the card available for informationpurposes and at the same time the frame is strength-. ened and stiffenedlongitudinally to better withstand the handling and pressure to which itis subjected.

What I claim and desire to secure by Letters Patent is:

1. A printing device frame made out of a single sheet of metal andhaving means to hold a printing device and an information card thereon,a portion of the frame behind the card bein cut on three sides and bentover upon t e frame to leave an opening disclosing the back of the cardand to strengthen and stiffen the frame, substantially as described.

2. A printing device frame made out of a single sheet of metal andhaving means to hold a printing device and an information card thereon,said frame having an opening therein to disclose the back of the card,part-s of the frame cut out to form said opening being bent upward anddownward respectively and against the front of the frame to formcontinuous strengthening and stiffening beads 'at the longitudinal edgesof said opening, substantially as de- WM. 0.
